Hiya,
I'm trying to get some of the custom shaders working on my linux box - especially the mix8layer and dirtmap shaders - so far with no luck :cry: I've looked round the web - but haven't found a solution.
I'll go through my steps so far... (concentrating on mentalray standalone because it seems to be able to give a more verbose output)
Attempt 1: - from a precompiled download
x Copied the dynamic library (.so) part into my mentalray/lib directory
x Copied the mentalRay include (.mi) part into my mentalray/include directory
x Added
link "{SHADERBASE}/lib/mix8layer.{DSO}"
mi "{SHADERBASE}/include/mix8layer.mi"
to my ray3rc file.
Trying to render gives the following link error:
LINK 0.0 error 191006: failed to load library <cut> mix8layer.so: undefined symbol: __gxx_personality_v0
When the mi file is read, no suprise, it can't find the mix8layer function.
Digging around this seems to be related to having been compiled with gcc rather than g++. As I had the source I moved onto...
Attempt 2: - compiling source
x Compiled source (basing on the Makefiles from the mentalRay devkit) using g++ for the linking.
x Copied over previous library
Trying to render gives:
LINK 0.0 error 191006: failed to load library <cut> mix8layer.so: cannot open shared object file: No such file or directory
I've checked the MI_LIBRARY_PATH is pointing at the right place - and everything else I can think of. Including opening the permissions up (chmod 777) copying the .so to /lib - playing with ld.so.conf - and even turning on LD_DEBUG.
At this point I'm stuck and probably just need advice from someone who has done this before. I'd also love to know a good place to look to start writing shaders from scratch. Have found bits and pieces but nothing particularly helpful.
Thanks for any help
